Abstract :
This paper addresses the problems concerning the fault-tolerant distributed replication of a controlling application in an automated system. The Manufacturing Message Specification (MMS) is used as a communication protocol between the controlling application (MMS client) and the automated industrial equipment (MMS servers). A distributed systems toolkit (DST) is used to manage the replication of the controlling application. We identify potential obstacles in the MMS environment when passive client replication is used. We suggest methods that the recovering client can use to overcome these obstacles. The solutions and alternatives proposed are discussed with respect to their conformance to the MMS standard
